Apr 8th 2020 AMD 4th Gen Ryzen Desktop Processors to Launch Around September 2020 (56).Version 31.0.101.3222 appears to be a transitioning point, and so it has drivers from both branches included within a 1.1 GB package (the main branch supporting game optimizations for new GPUs, and the legacy branch for the older iGPUs).

Intel's regular Graphics Driver cycle that includes Day-0 optimizations timed with new game releases, will only cover the Gen12 Xe iGPUs found in 11th Gen 'Tiger Lake,' 'Rocket Lake,' and 12th Gen 'Alder Lake' processors besides the DG1 Iris Xe graphics card and Arc 'Alchemist' discrete GPUs. Support for Gen9, Gen9.5, and Gen11 iGPUs integrated with 6th, 7th, 8th, 9th, and 10th generations of Intel processors, namely 'Skylake,' 'Kaby Lake,' 'Coffee Lake,' 'Ice Lake,' and 'Cascade Lake,' will be relegated to a separate, quarterly driver update cycle, which only covers critical updates and security vulnerabilities, but not game optimizations. The company would be providing game optimizations and regular driver updates only for its Gen12 (Iris Xe), and Arc 'Alchemist' graphics products. Intel Graphics, with its latest Graphics Drivers 31.0.101.3222, changed the coverage of its latest driver updates.
